Hoban Hot Mix Asphalt

SECTION 2: Hazards identification

WARNING! HOT MIX ASPHALT IS NOT A KNOWN HEALTH HAZARD. HOWEVER HEATED MATERIAL CAN CAUSE THERMAL BURNS. FUMES MAY BE IRRITATING TO THE EYES, NOSE, AND THROAT. THIS MATERIAL CONTAINS AGGREGATE, A NATURALLY OCURRING MINERAL COMPLEX THAT MAY BE SUBJECTED TO VARIOUS NATURAL OR MECHANICAL FORCES THAT PRODUCE SMALL PARTICLES (DUST), WHICH MAY CONTAIN RESPIRABLE CRYSTALLINE SILICA (PARTICLES LESS THAN 10 MICROMETERS IN AERODYNAMIC DIAMETER). REPEATED INHALATION OF RESPIRABLE CRYSTALLINE SILICA (QUARTZ) MAY CAUSE DAMAGE TO LUNGS THROUGH PROLONGED OR REPEATED EXPOSURE AND MAY CAUSE LUNG CANCER. PRODUCT CONTAINS PETROLEUM ASPHALT. THE INTERNATIONAL AGENCY FOR THE RESEARCH OF CANCER), CLASSIFIES PETROLEUM ASPHALT FROM PAVING OPERATIONS AS A “POSSIBLE HUMAN CARCINOGEN GROUP 2B” THE NATIONAL TOXICOLOGY PROGRAM (NTP), LISTS – EMISSIONS FROM PETROLEUM ASPHALT AS “REASONABLY ANTICIPATED TO BE A HUMAN CARCINOGEN

2.1 Classification of the substance or mixture

SKIN IRRITATION- Category 2 , EYE IRRITATION – Category 2 CARCINOGENICITY/INHALATION — Category 1A SPECIFIC TARGET ORGAN TOXICITY (EXTENDED EXPOSURE) ) — Category 2

Signal word

Danger

Hazard statements

Harmful if swallowed. Causes skin Irritation. Causes eye irritation. May cause cancer (inhalation). May cause damage to lungs with prolonged or repeated exposure (inhalation). EMERGENCY OVERVIEW:

Appearance/Odor

Dark gray to black material, slight sticky and oily surface, typically in pea gravel sizes. Slight oily odor. WARNING Carcinogen, Acute & Chronic Toxin Warning • This product contains greater than 0.1% crystalline silica. Crystalline silica has been linked to cancer, silicosis, and other lung problems in conditions of prolonged airborne over- exposure. Repeated inhalation of respirable crystalline silica (quartz) may cause lung cancer according to IARC and NTP; ACGIH states that it is a suspected cause of cancer. Other forms of RCS (e.g.,tridymite and cristobalite) may also be present or formed under certain industrial processes. • Carcinogen- Acute & Chronic. Product contains crystalline silica quartz. The International Agency for Research on Cancer (IARC) classifies respirable crystalline silica as Group I – Known Human Carcinogen. The National Toxicology Program (NTP) lists respirable crystalline silica as a Known Human Carcinogen. The American Conference of Governmental Industrial Hygienists (ACGIH) lists respirable crystalline silica as a Suspected Human Carcinogen (A-2). • Product contains petroleum asphalt. IARC classifies emissions of petroleum asphalt from paving operations as a “Possible Human Carcinogen Group 2B”. The National Toxicology Program (NTP) lists – emissions from petroleum asphalt as “Reasonably Anticipated to be a Human Carcinogen. Exposure to thermally generated petroleum asphalt fumes may be irritating to the eyes. OSHA REGULATORY STATUS: This product is considered HAZARDOUS by the OSHA Hazard Communication Standard (29 CFR 1910.1200).

Principle Routes of Exposure

Inhalation TARGET ORGAN(S): Lungs EYE • Avoid eye contact. Exposure to dust may be irritating to the eyes and may impair visibility. Exposure to thermally generated fumes may be irritating to the eyes. SKIN • Avoid prolonged and repeated skin contact. Exposure to dusts may be irritating to the skin by chemical or mechanical means. This condition may be aggravated by perspiration or moisture. • Prolonged or repeated contact with petroleum asphalt may result in dermatitis, which is characterized by dryness, chapping, and reddening. Petroleum asphalt is associated with photosensitization, an abnormal sensitivity of skin to sunlight. INHALATION • Avoid prolonged and repeated inhalation of fumes or dust. Acute and chronic exposure to dusts may be irritating to the respiratory tract by frictional action, and may provoke bronchoconstriction in hypersusceptible individuals. • Respirable dusts can cause bothersome deposits in the nasal passages. Nuisance dusts cause toxicity from physical overloading of the respiratory clearance mechanisms. • Significant deterioration of pulmonary function and chronic bronchitis can develop with prolonged overexposure to dusts in excess of established limits (See Section 8). • Continued overexposure to silica dust can result in silicosis, a chronic, progressive and sometimes fatal lung disease that is characterized by the presence of typical nodulation of the lungs leading to fibrosis. Silicosis can develop in weeks with high exposures and after years of lower exposure. Symptoms and signs of silicosis include cough, shortness of breath, wheezing, decreased pulmonary function, and changes in chest X-rays. • Thermally generated petroleum asphalt fumes may be irritating to nose and throat and may cause nausea. AVOID BREATHING DUST OR FUMES. IF POSSIBLE, USE THESE PRODUCTS FROM AN UPWIND LOCATION. IF DUSTY CONDITIONS CANNOT BE AVOIDED, WEAR A NIOSH/MSHA APPROVED RESPIRATOR. INGESTION • Minute amounts accidentally ingested during industrial handling are not likely to cause injury. Rinse mouth thoroughly. Do not induce vomiting without advice from poison control center 1-800-222-1222. If vomiting occurs, keep head low so that stomach content does not get into the lungs. Never give anything by mouth to a victim who is unconscious or is having convulsions. Get medical attention immediately.

Medical Conditions Generally Aggravated by Exposure

Chronic exposure to nuisance dusts may enhance susceptibility to respiratory tract infections. • Silica can cause silicosis which, in turn, increases the risk of pulmonary tuberculosis infection. • Smoking may increase the risk of developing lung disorders associated with silicosis. • Chronic skin exposure to petroleum asphalt can aggravate pre-existing skin disorders.
